Hi,
I have a problem with my microphone which was really weak. I can't have calls because people don't understand what i saying.
So i decided to change my USB Board. I buy one from eBay, but after changing it, the microphone is still weak
I tested both microphone directly with the phone disassembles, and it works correctly. But when I reassemble the phone, the microphone does not work (it is really weak).
Does anyone know where it can come because I do not really understand the problem.
Thank you.
Try cleaning the mic's hole on the case.Maybe there is a little dirt stuck.

Already tried, the hole is totaly clear
bkd35,
I have exactly the same problem. Nothing changed after replacing this USB board also. It seems that mic is working but all it records is way to quiet. I was checking that with voice recorder, it records sounds when I yell into that small hole.
Everything is perfectly clean, no dust anywhere. Also I checked if the problem still exists after reinstalling android, after going through many roms, stock and custom ones nothing changed.
What is more interesting, for me sad, I was looking for a solution on many forums and all people can say is to use service codes but they don't work for me. Guys, any ideas what to do? Thanks
EDIT: oh and by the way, maybe it would be better if this thread would be "low microphone volume" or something like this

Hey guys, I have a hardware issue but first the background story
So my phone fell on concrete and the screen broke. I bought a digitizer and replaced it myself. After a month or so, I broke it again. I replaced it, but the unit I got was faulty, and I only got the replacement today.
I opened the phone again and replaced the digitizer, and it's working great!
however in the process I must have done something wrong since my audio/sound doesn't work anymore.
1)Loud speaker works just fine and the microphone works since I am able to talk to people and they hear me
2) When I plug in my earset, the sound works just fine on the earphone. The microphone switches over the earset's microphone and I can hear/talk just fine.
The only problem that I have is I can't hear anything if i put phone next to my ear :/ I opened again looked around, but didn't find anything obvious that might explain wha went wrong. Would anyone know where to look/what to test?
Cheers
anyone any idea please? D:
I haven't opened up my Mozart just yet but from my experience with HTC phones I would suggest checking the contacts of the speaker. They tend to have little springs on the speaker that come in contact with the mainboard and this is how the signal is transmitted. If these contacts are damaged then you will not hear anything.
With all the drops you may have damaged the speaker itself but I'm not sure of a way you could test that.
The problem i had was that I used my sony ericsson X8 headset and the sound came out funny, the thing that was cuasing it was the microphone. Try stock headset to see if it works. If it doesnt then you might want to get someone to check it or fix it. Up to you.
Has anyone had issues with the external speaker on the i9100?...
Mine will sometimes work for a few seconds then cut out...sometimes it won't even do that, just emitting a "click", like when you unplug a connection...ringtones never work (ever)...(and no, it's not on "silent")
The headphone jack works fine (and has been replaced already), and I've tried the "plug in plug out" solution. The call speaker (against the ear when on a call) works fine, and the Mic works fine....
I'm running cm10 and the latest siyah kernel, but this was happening when I was on stock and not rooted....
I replaced the speaker, and it worked perfectly for a day or so, then....not so much
Everything else is smooth as, and it's a great phone....would just be nice to be able to hear it ring is all...

did you recheck your speaker? maybe there was a loose wire or something.. there is a possibility that it may be a motherboard problem but i highly doubt it

Replace the USB flex cable board. I had the same exact problem. It instantly fix it but swapping that board my bring signal problems. Then refer to this thread.

all good now! i replaced the usb flex. when comparing the two boards, the new one has a slight curve in it that seems to bring the contacts closer to the speaker ...don't know if it's by design, but it works....my phone rang for the first time in ages this morning, and it scared the crap out of me
So I installed Neutrino on my Atrix yesterday (I'm not sure if that's relevant or not, but I figure it's good to know), and everything was working perfectly fine. However, earlier today the audio from my headphone jack started to sound completely distorted.
It's not the earbuds, because they work on other devices I have. And the audio from my speakers and from HDMI works perfectly fine.
Has anyone had this problem, and if so, is there any way I can fix it? Or is my phone screwed?
Did you play with equalizer settings any (DSPmanager or similar)?
I didn't. At least, not at first.
DSP Manager actually started to crash on startup about the same time that the audio from my headphones would be a problem. I thought reinstalling it would fix the problem, but it hasn't. Though, the louder I make it, the more "clearly" I can hear what I'm playing (it still sounds like satan farts, though).
I also tried cleaning the headphone jack, but that only helped a slight bit.
Would it be worth reinstalling Neutrino or is my phone died?
I'd say it's worth a shot. Make a nandroid, do a full wipe, and then flash your ROM. If that doesn't help, then at least you can be fairly sure it's not the software.
So I'm bumping this, with a little bit more information of what I've tried and what my problem is.
I've tried uninstalling and reinstalling DSPManager. Didn't work.
I made a Nandroid backup, did a full wipe, and tried to play music again. Didn't work.
I actually tried to install Beats Audio Drivers to see if they would help. They didn't.
This is what my phone's audio jack currently sounds like, without the high-pitched humming so pardon me if your ears hurt.

I actually tried cleaning the inside of my headphone jack and it seemed to help ever so slightly.
Would this mean my headphone jack is toast or does anyone else have any ideas what the problem could be?

I'm not sure, but it sounds like what you're hearing is the difference between the 2 channels, rather than the channels themselves. This would happen if the common ground connection is broken somewhere in the audio out. It's an easy theory to test really. All you need is an audio file that plays on either the left or right channel only. If you have sound out of both channels, then there's your problem, if not, then it's something else.
Actually, this sounds like a poor connection that is overcompensated by extreme loudness so that some of the electric current is strong enough to pass through. I've heard what the "no common ground" sounds like many times, I don't think this is it.
The headphone connector is not actually soldered to the PCB but instead sits on it on springy contacts (makes for very easy repairs and replacements at service centers). I'm almost willing to bet there lies your problem.

Maybe. But if that is the case, wiggling the plug may give some indication of that without disassembling the device, just as would playing a single channel file. In both cases, the jack would likely be the culprit, but given how fragile the device is internally, taking it apart should be done with extreme caution.

True. I wouldn't recommend digging into disassembling the phone right away, not before exploring other possibilities. Because...

I tried playing a mono sound file, and sound files that play through only the left speaker and only the right speaker. They all sound like they have the same problem, so we can rule that out.
Though, I will mention that the sound that is heard is on maximum volume, and that's the only time I can hear anything at all. If I go down just two notches, then I start to hear nothing.

Just a thought, but have you tried another pair of headphones?
Edit: if the headphones are good, then the only other thing I can think of is a bad section in the audio chip. The schematic shows the headphone output is separate from any of the other sound outputs, so it is possible that the chip is bad. Unfortunately, if that is the case, the cheapest solution would be to replace the main board, but it's a delicate procedure.
Edit 2:
Before giving up, this thread might help.

Yeah, I'm sure it's not the headphones. I've got two; a set of headphones and a set of ear buds. Both of them are functional in other devices but do not work in the phone. Also, the audio clip was direct feed with a different chord, so the problem is surely with the phone.
I'm at the point where I'm willing to open up the phone to see if there is a problem with the jack itself. If it is corrosion or another problem with the jack then I can try some repairs. If I do have to replace the main board then I'll probably wait on that and ultimately purchase a new phone.
One thing to note is that the audio quality does not improve if I move the jacks around inside of it. However, I do hear a sort of rubbing sound from the headphones if I am moving it around.

If the jack is the issue then it shouldn't be too bad to replace. I was looking at different websites earlier and they look to be really cheap. The thing I have to stress though is just be careful, and don't take apart the phone unless you can replace the phone itself just in case something should go horribly wrong. I know that should be pretty obvious, and generally people tend to underestimate their own skill level, but I have encountered a few people in my time who have what I consider to be the opposite of the Midas touch, and their attempts at repairing anything end up as more of a hate crime against the very thing they are trying to fix.
My Amaze 4G for T-Mobile was rooted with s-on and flashed with Revolution HD 4.0 about half year ago. I had to change the digitizer/LCD assembly because it went dark. That went rather smoothly. However, the mic stopped working after that. I can hear people but they can't hear me. I did re-flash with the same ROM after the repair since the phone was having some other issues I thought might be software related. Didn't test the mic before the flash though.
The symptoms and what I've done so far:
-- People can't hear me during call. Turning on speaker doesn't help. Using a headset with built-in mic works.
-- The voice recorder app can't record a thing. Tapping the phone doesn't record either, so it's not dirt blocking the hole. AndroSensor app shows no sound input.
-- I can record video WITH sound. This was actually done after I replaced the mic PCB. Does this mean the mic is OK or the phone has another mic?
-- Re-flashed and tried another ROM, same thing.
-- Flashed back to stock T-Mobile ICS ROM, no good.
-- Installed SoundAbout app, played around with it, i.e., the headset plug trick, still no dice.
Since I can record video with sound, I feel it's more like a software problem, unless there's a secondary mic used for video recording but not phone calls. The sound doesn't seem to be recorded through the mic hole at the bottom as blocking it with my finger doesn't reduce the volume. I'm thinking to try the stock Gingerbread ROM as a last resort.
Any input will be greatly appreciated.

Since the Amaze records video in stereo, I have to assume there are at least 2 mics.

Make sense. It was working fine before I changed the digitizer/LCD. Thought I might broke something during the process. Checked the cables and they looked OK, so I replaced the microphone PCB but that didn't help. Could be a bad PCB though. May try to ask seller for a replacement. Does the problem sound like a software issue to anyone? I went ahead re-flashed the stock GB ROM but failed. I read somewhere the phone needs to be S-Off to do that. Any suggestions what else I can try to fix it?

Not a notion. It would be nice if there was some sort of schematic or youtube how-to for the mic. As for getting to S-Off, there is guide if necessary--do a search.

Replacing the mic PCB was easy, figured it out by myself. Can't be sure if I broke something else during the repair. I did search for S-Off guides and it seems the wire trick under Linux is the only way to go now. Since putting back the stock ICS ROM didn't help, I don't think the stock GB ROM will do any good either. The phone had ICS when I rooted it. Requested a replacement of the mic PCB I bought, let's see how that goes.

Hi. I have a very strange issue on my device.
Whenever i plug in an earphone/Headphone, i can listen to the sounds ONLY from the left earpiece.
I cross checked the earphone with my desktop, laptop and others' phones. It is working perfectly.
I just need to know if this is a software related issue or a hardware issue.
I tried changing my ROM in case the current ROM had problems. Even after changing to a different ROM, the problem persisted.
Any help would be appreciated.
Thank you.
Sounds like a hardware error to me if you are having the issues with different ROMs. Try different headphones. If they don't work it MAY be the jack. But nothing is for sure here. :-/

I tried with different headphones too. Problem remains. The jack?
If you have the knowledge, could you share with me what MIGHT have happened? A GUESS?
Sorry,
the jack for me (I'm German) is the hole you stick your headphones into.
Unfortunately after some time and maybe some rough treatment the jack gets damaged. Google "repair headphone jack" and you will find many people with that problem.
If you can not fix the issue by any software and the headphones themselves are working it is most probably a hardware failure on the phone, jack is dislocated/broken a bit.
Google and maybe even repair service is your friend now from what I can tell. :-/
First try to clean the phones jack. Sometimes, garbage gets inside preventing good contact between the earpiece and the phone's jack. Use a toothpick or something (preferably not something metallic) to scrub it and see if it works.

Thank you. I will try that.
If this doesn't work, can it be solved without getting it to a service center?
Because i have lost my warranty due to physical damage almost 8 months back.
It worked fine till last week, but somehow this started.

If its not garbage, its hardware damage. You'll need to get it replaced. Luckily, replacing the jack is usually very cheap.
